1. Remove the upper center instrument panel finish panel.
2. Remove the passenger air bag module. See «PASSENGER AIR BAG MODULE REMOVAL/INSTALLATION»(ref-373086-S41914677292010100600000)
3. Working through the passenger air bag module opening, remove the RH panel duct screw.
4. Working through the passenger air bag module opening, remove the upper RH center panel duct screw.
5. Remove the lower RH center panel duct screw. Detach the wire harness pin-type retainer. Remove the lower RH center panel duct screw. NOTE: The lower RH center panel duct screw is located just below the RH lower rear corner of the audio unit.
6. Working through the glove compartment opening, detach the wire harness pin-type retainer above the evaporator discharge air temperature sensor.
7. Disconnect the RH temperature blend door actuator electrical connector. CAUTION: Use care to avoid dropping the RH temperature blend door actuator screws into the plenum chamber when removing the screws. If a screw is dropped into the plenum chamber, it may cause the airflow mode doors to jam, or may cause noise concerns.
8. Remove the 2 RH temperature blend door actuator screws. To install, tighten to 3 N.m {0.3 kgf.m, 27 in.lbf}.
9. Remove the RH temperature blend door actuator. NOTE: The RH center instrument panel duct must be slightly repositioned to allow access to the RH temperature blend door actuator screws.
10. To install, reverse the removal procedure.
